PASTING DEVICE FOR PACKAGING MACHINES.

Application filed. August 15, 1922. Serial No. 581,953.

T 0 all whom it may concern:

Be it known that I, EUGENE G. KERLIN, a citizen of the United States, residing at Salem, in the county of Roanoke and State of Virginia, have invented certain new and useful- Improvements in Pasting Devices for Packaging Machines, of which the following is a specification.

.This invention relates to pasting devices for packaging machines.

The object of the invention is to apply to the outside wrapper along the longitudinal edges thereof a strip of glue, whereby the outside wrapper when folded around the package is held in place.

A further object is to apply glue to the outside wrapper in such a manner that, when it is folded around the foil covering, which has been previously folded, it will stick to the foil covering and hold the two wrappers together.

A further object of the invention is to provide means whereby the strips of paper are passed through the pasting machine at predetermined intervals.

In the accompanying drawings Fig. 1 is a side elevation of the device;

Fig. 2 is a top plan. view thereof;

Fig. 3 is an end view thereof;

Fig. l is a perspective view of the adjustable yoke.

The numeral 1 indicates a base provided with an integral inside standard 2, and an outside standard 3 detachably secured thereto by suitable spacer bolts 4. Extending laterally from the inside standard is a gluepot 5. Arranged above the glue-pot are two sets of delivery rollers 6-6 and 7-7 secured to a shaft 8, the latter being journaled eccentrically in an adjustable yoke 9, the laterally-entending trunnions 10 and 11 of which are received in suitable bearings 12-12 in the standards 2 and 3. The numeral 13 indicates a shaft journaled in suitable bearings 1% and 15, received in suitable openings 16, 16, in the upper part of the standards 2 and 3.

These bearings are grooved as at 17-17 along their vertical edges, being adapted to encircle the vertical inside edges of the opening 16, and beneath the vertical adjustable bearings are arranged compression springs 18 upon which the bearings rest. The open end of the opening 16 is closed by a cap 19 which is provided with a verti-v cally-adjustable set-screw 20 provided with a lock-nut 21 said set-screw engaging the top of the bearing whereby the latter may be adjusted vertically.

Secured to the shaft 13 is an outside set of transfer rollers 22-22 and an inside set- 23-23, which engage the periphery of the delivery rollers 6-6 and 7-7 respectively, the latter serving to deliver glue from the glue-pot to the transfer-rollers.

A scraper 24 is arranged upon the top of the glue-pot and is preferably provided with a plurality of slots 25 to receive the delivery rollers 6-6 and 7-7, the scraper preferably being horizontally adjustable, whereby the amount of glue picked up by the delivery rollers may be governed.

The numeral 26 indicates a shaft journaled in the standards 2 and 3 and secured thereto are the paste applying disks 27-27, which are of such a diameter to contact with the periphery of the outside transfer rollers 22-22. The applyingdisks being so positioned as to project below the paste-pot 5, permitting the wrappers used in the packaging machine to which this pasting device is to be attached to pass horizontally beneath the glue-pot and beneath the applying disks which in turn distributes the glue along the edges of the wrapper. It is desirable to rotate the several rollers and applying disks. To accomplish this, I preferably secure to the shaft 26, to which the applying disks 27-27 are secured, a drivepulley 28. A. gear 29 also secured to the shaft 26 is adapted to mesh with a gear 30 secured to the shaft 13 carrying the transfer rollers 22-22 and 23-23. said 30 in turn meshing with a gear 31 secured to the shaft 8 carrying the delivery rollers 6-6 and 7-7, the arrangement constantly rotating the several rollers and disks.

During the wrapping of the articles, it is desirable to apply glue to one of the flaps of the folded end of the wrapper surrounding the articles being packaged. To accomplish. this, the shaft 26 is supported in suitable bearings 32 on the box 33, and mounted on the shaft 26 is a rocker-arm 3 carrying on the outer end thereof a stubshaft 35, upon which is rotatably mounted a member 36. Extending laterally of this member are arms 37-37 between which is mounted the secondary applying-rollers 38-38.

Keyed to the shaft 26 is a pinion 39 adapted to engage a rack-bar 4O horizontally slidable in the base 33, to which is imparted a reciprocating movement by means of a cam 41 which engages the outer end of a rod 42 secured at its inner end to the rack-bar 40. The cam 41 is operated by means of a belt and pulley, not shown. Ex-

tending laterally from the member 36 is an arm 43 carrying a transverse pin 37 which, when the arm is in the lower dotted ime position in Fig. 1, bears against an abutment 44 integral with the arm 34 holding the rollers 3838 in their lowermost-position 'with the assistance of the spring 45, one end of which is secured to the arm 43, while the opposite end is secured to a lug 46 integral with the rocker-arm 34.

As the rack-bar .40 is reciprocated, the rocker-arm 34 is moved upwardly carrying with it the pasting-rollers 3838; near the upper end of the stroke the arm 43 strikes an abutment 47 extending transversely of the standards 2 and 3, causing the pastingrollers 3838 to swing inwardly and con tact with the central transfer rollers 2323, receiving a coating of glue whereupon the reversed movement of the rack-bar 4O swings the pasting rollers 3838 downwardly, into their lowermost position, applying glue to one of the extended portions of the wrapper about to be sealed.

The several rollers 6-6, 77, 2222, 23-23, and the paste applying disks 27-27 are rotated continuously on the shafts 8, l3 and 26 by means of the pulley 28 and the intermeshing gears 29, 30 and 31. The paste applying disks 2727 are in contact with the transfer rollers 2222, receiving glue therefrom, and apply glueto the wrappers as they pass under the disks.
